HALTOM M. STROUP, OF PINEVILIiE, NORTH CAROLINA.

GIN-SAW CLEANER.

To all whom it may concern: Be it known that I, HALTOM M. STROUP, a citizen of the United States, residing at Pineville, in the county of Mecklenburg and State of North Carolina, have invented certain new and useful Improvements in Gin- Saw Cleaners, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in cotton gin saw cleaners and has for its object to provide a very simple and efficient device of this character which will cleanly remove the cotton from the throats of the saw teeth so that the cotton may be cleanly re moved from the seed in the operation of the gin.

A further object of my invention resides in the provision of a rotary steel wire brush movably mounted in the gin frame adjacent to the gin saws, and means for moving said brush into and out of operative position.

A still further object of the invention is to provide an auxiliary cleaning brush extending longitudinally beneath the saws, driving means for rotating said brush, and means for moving said brush to an inoperative position together with the means for driving the same.

With these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is an end elevation of a gin saw cleaning machine showing my improved cleaning attachment arranged thereon; Fig. 2 is a similar view, showing the cleaning saw in its inoperative position; Fig. 3 is a side elevation of one end of the machine. Fig. 4 is a detail fragmentary perspective view of the supplementary cleaning brush and operating parts.

Referring more particularly to the drawing 5 indicates the gin frame in which a plurality of gin saws 6 are mounted upon the transverse shaft 7. A brush 8 is also mounted in the frame 5 upon the shaft 9. Power is applied to one end of the saw shaft and to the brush shaft in the usual manner, a suitable driving connection connecting the ends of said shafts. The construction and arrangement of the parts above described is very common and forms no part of the present invention.

Serial No. 571,473.

WVhen the cotton becomes damp or wet, the throats of the saw teeth often become choked thus greatly impairing the efficiency of the gin and rendering the clean removal of the cotton from the seed practically impossible. My invention is devised with a view to remedying this difliculty and embodies in its construction a transversely disposed brush 10 which is of considerably smaller diameter than the saws 6 and is arranged beneath the same. This brush is preferably formed of steel wires which ex tend into the teeth of the saw and between the saw blades, said brush rotating in an opposite direction to the saws. The brush 9, a drive belt 11 extending over a band wheel on the end of the shaft 9 and around a similar band wheel on the shaft of the brush 10. Means are provided for simultaneously moving the brush to its operative position with relation to the saw and tightening the drive chain to rotate said brush. This means comprises a lever 12 which is pivoted upon the side of the gin frame as indicated at 12. The greater portion of this lever extends rearwardly of the saws and has mounted in its rear end a guide wheel 13 around which the drive belt 11 passes. The forward end of the lever 12 carries the shaft of the brush 10, said shaft being mounted to rotate therein. The other end of this shaft may be supported by a pivoted arm or in any other desired manner to allow the brush to move in an arc. A lever 14 is pivotally mounted upon the front of the gin frame at one side thereof. This lever has an angularly and rearwardly extending end 14' and to the extremity thereof and the shaft of the brush 10 a link 15 is connected. This link is pivoted to the end of the lever 14 and the shaft is rotatable therein.

In the operation of the machine it will be observed from reference to Fig. 1 that upon the application of power, the brush 10 is r0- tated in a direction opposite to the gin saws in a similar manner to the main brush 8. My improved cleaning device is used only when the cotton is damp or wet and the brush 8 is not capable of removing the lint from between the teeth and the saw blades. \Vhen such is the case, the lever 14 is moved into the position shown in Fig, 1 and the brush 10 elevated to contact with and extend between the saw blades. At the same p 10 is driven from the stationary brush shaft time the lever 12 will be oscillated and the rear end thereof which carries the guide wheel 13 thrown downwardly whereby the drive belt 11 is tightened so that the necessary friction is secured between the same and the various band wheels to drive the rotary cleaning brush. The wet or damp cotton which has accumulated in the throats of the saw teeth and between the blades will thus be removed as the saws rotate. When the use of my improved cleaning device is no longer necessary, the lever 12 is moved upwardly to the position indicated in Fig. 2 whereby it will be noted the cylindrical rotating brush 10 is thrown downwardly and the rear end of the lever 12 which carries the guide wheel 18 is elevated thereby loosening the driving belt and discontinuing the rotation of the brush 10.

From the foregoing it will be readily seen that I have devised a very simple and eflicient cleaning mechanism for gin saws which is essential to the successful operation of the gin when the cotton is damp or wet and eliminates the necessity of removing the cotton, which accumulates in the saw teeth and between the blades, by hand, thereby saving considerable time, labor and expense. The auxiliary brush may be easily and quickly moved into and out of its operative position and the connection whereby the same is driven automatically effected. Owing to the very few elements employed in its construction and the simplicity of their arrangement it will be obvious that the device may be constructed at an extremely low cost. It is also very durable and highly efiicient in practical operation.

While I have shown and describedthe preferred embodiment of my invention, it will be understood that the sameis suscep- Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

tible of many minor modifications without departing from the essential feature or sacrificing any of the advantages embodied therein.

Having thus described the invention what is claimed is The combination with a gin frame having a plurality of saws rotatably mounted therein, of a primary cleaning brush rotatably supported in the frame for engagement between the s'aw blades, a supplementary brush disposed beneath the saw blades, an oscillatory lever pivoted on the frame intermediate of its ends, said supplementary brush being rotatably supported in one end of the lever, a friction wheel mounted on the other end of said lever, a band wheel fixed on each of the brush shafts, a driving belt passing around 'said wheels, said friction wheel on the end of the lever being disposed for movement between the stretches of said belt and adapted for engagement with the same, an angular operating lever pivotally mounted upon the frame, a link rod loosely connecting one end of said operating lever and the oscillatory lever to simultaneously move the supplementary brush into engagement with the saw blades and frictionally' engage the friction wheel carried by the oscillatory lever with said belt to tighten the belt and rotate the supplementary brush, and means connected to a suitable source of power supply for rotating the primary cleaning brush.

In testimony whereof I hereunto afiixmy signature in the presence of two witnesses.
